This paper will consider the impact of carbon and oxygen content on Nitinol alloys for medical applications. Four alloy melts were chosen to yield varying levels of oxygen and carbon content and were subsequently drawn to yield representative wire and tubing sizes for typical medical device applications. A series of processing experiments, fatigue tests and corrosion tests were performed in order to study the implications for medical device manufacture and in-vivo durability. | ||
